Abstract

fetched live from OpenAlex

Peganum harmala L. (Zygophyllaceae) is a common plant in Middle East and it is still used traditionally to treat several diseases. The effect of P. harmala extract on the expression of different cytochrome P450's (CYP) involved in drug metabolism was examined in human HepG2 cells. Therefore, HepG2 cells were incubated with increasing concentrations of plant extract and the CYP gene expression was determined by real-time PCR. Our results showed that P. harmala extract significantly increased the expression of CYP1A2, 2C19, and 3A4 whereas; CYP 2B6, 2D6 and 2E1 was significantly decreased. We concluded that care should be taken when P. harmala is co-administered with other drugs.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
